If there is wind, I know that leaving your kite inflated will damage the trailing edge of your kite over time in the same way the wind weakens the material of a flag. I have had two kites that I have left in the wind too long as I relaxed between sessions. And, over time, the trailing edge began to come apart/rip and I had to have the trailing edge reinforced.

But yes, it is very nice to wake up to an inflated/ready to be flown kite. So perhaps it is well worth leaving the kite inflated!

(As far as damage to the bladders/valves, I am interested to see what people say as well).

Not a problem for me - kites are stored in a protected shelter - so no wind or sun damage can occur. But yes, I take your point.

I have some friends that leave their struts inflated all the time, and there doesn't seem to be much of an issue. We replace kites with new ones fairly often though, so I'm not sure about long-long-term.

I believe the only potential problem you could run into is if the heat changes too much which causes the pressure to change inside the bladders (IE, leaving the kite in a hot garage). If it's indoors in a stable temp it's probably fine
